The impact of final-state radiation (FSR) on the radiative
return method for the extraction of the e+e- hadronic cross section
is discussed in detail. Possible experimental tests of the model
dependence of FSR are proposed for the pi+pi- hadronic final state.
The importance of the (pi+pi-photon) final state contribution
to the muon anomalous magnetic moment is investigated,
and a method based on the radiative return is proposed
to extract these contributions from data.
